Abstracts

EN

High crystalline quality films of n-La_{2/3}Ce_{1/3}MnO_3, p-La_{2/3}Ca_{1/3}MnO_3 and related p-n diode structures were grown heteroepitaxially on lattice-matched SrTiO_3(100) substrates by dc magnetron sputtering and pulsed laser deposition. The La_{2/3}Ce_{1/3}Mn O_3/La_{2/3}Ca_{1/3}MnO_3 bilayer was patterned into a strip-like geometry to investigate electrical properties of the interface. Significant magnetoresistance values and nonlinear current-voltage characteristics were indicated for the interface of the p-n diode heterostructure.
